Theater Groot huis
The name means 'Big House' and it's a classically 19th century theater with red carpet, balconies and shiny gold. Before or after the show you can visit the Foyer (restaurant with terrace overlooking the Sint-Baafs square).

Boat trip II
Do you want to be the captain of your own boat and sail through the waters of Ghent? Maybe you want to take your own picknick basket? You rent it for 45 Euro for 2 persons for 2 hours. I didn't do this myself but it seems like fun. I keep it in mind for next time.

Guided walks
You can choose from several guided tours. Even a Pub-crawl belongs to the possibilities (to be booked in advance). The 'normal' guided city walk leads you trough the inner city with the historical buildings and monuments. Subscription and start is at the Belfry.

Shoes
Be sure to wear comfortable shoes...avoid high heels. The fact is that the streets of Ghent are paved with large cobblestones ('kinderkopjes'). They are difficult to walk on (high-heeled shoes as well as the stones).
